1973-1987 GM Trucks LS Conversion Kit

This swap kit is for 1973-1987 GM ½ ton 2 wheel drive trucks and 1973-1991 2wd SUV. It was designed around our GM LH8 oil pan. Unlike most LS swap parts on the market this kit replaces the frame brackets in addition to the mounts so you'll have clean mounting of your engine and not a mix of parts that are weak and don't work together properly. The frame brackets bolts into existing holes in the frame and and locates the engine to give you the most options for front accessories drives. Unlike others, our kit positions the engine so there is no steering interference and maintains the proper drive-line angle for smooth highway cruising. It provides clearance for the factory AC box, power brake booster, and aftermarket suspension components. We offer a complete line of headers that give unparalleled performance and ground clearance with sizes that are matched to your engine combo. These combined parts offer an easy, strong, and clean installation of your LS engine. See our installation guide for more info on this LS swap.

The oil pan our kit was designed around. Comes standard or machined for the oil bypass valve for use with displacement on demand or variable valve timing. Includes new full length windage tray, pickup tube, hardware, gasket, dipstick, and our pickup tube girdle.

Oil Pump Pickup Tube Girdle

Original GM oil pickup tubes are fastened to the pump with only one bolt with a tear drop shaped mating flange on the tube. There is another threaded bolt hole on the other side that is not used. Our Girdle is cnc machined aluminum and goes over the original mating flange, wraps around the tube, and fastens using both bolt holes. Use with a little Locktight and it’s cheap insurance against an engine meltdown. It comes with two longer bolt for install.

These are not your average swap headers. These headers offer many feature that are normally only on custom race headers. We start with 3/8" laser cut flanges with the tubes welded inside and out and then machined. The long tube headers feature bolt-on race inspired collectors for ease of installation and tuning of primary length. The mid-lengths use a gasket-less ball and socket type collector for a leak free install. They're ceramic coated inside and out to fight performance robbing underhood temperatures then polished for a long lasting show quality finish.

We offer several sizes of headers so you can match them to your engine combination. Our 1 ¾” mid-length headers offer great ground clearance and support up to 500hp. Our 1 ¾” long-tubes will support up to 600hp. For more than 600hp we offer 1 7/8” long-tubes and for big cubic inch monster engines our 2" is a perfect match. Our stepped headers offer great high rpm performance while retaining good low and mid-range power. They all include gaskets, bolts, reducers, and O2 sensor bungs.

This kit does not include headers. You can upgrade to headers based on your power goals, or come back to order them when you are further along. In either case, you cannot go wrong!

Fast shipping, installed very easy. I am not a professional mechanic. Also I have yet to install the motor. Can not comment on fitment, but looking to be more than fine. I did not order headers. Wish I did. I will be ordering them from here soon.
